hey, if i removed the mufflers on my 95 riv supercharged, but kept the cat on it, and just ran pipes out the back, would i gain a little hp, also i wouldnt loose torque or boost would i?

also, what size pipe is on the 95 supercharged riv stock?

please visit the muffler thread in the series 2 section. You don't loose torque going to a bigger muffler. The torque curve just changes (higher in the RPM range).

Imo, the gains in HP from cutting off mufflers aren't spectacular. The way to get power out of the Series I SC is to increase boost and flow more air through. Mufflers aren't the most restrictive part in my experience.

maybe deleting one of the mufflers,and running only one through maybe a 3" pipe all the way to the down pipe might maintain low end tourqe and also high end? what do you think?? itl save a few pounds too!

I'm sure a muffler delete would give you a little power but probably not night and day , and there are better gains to be had with an intake , plus it will sound better than exhaust IMO.

Many modded rivs on this forum still run stock exhaust. AA for one is making about 300hp through the stock resonator and mufflers.

I've only ever put exhaust on v-8's that I've owned, and always loved Flowmaster's. Dont know about a v-6 though, they're hard to make the exhaust sound good.
